SNOW-PLOW FO R STREET-RAI LWAYS.

SFECIFICATION forming part of Letters Patent No. 574,875, dated January12, 1897.

Application filed October 17, 1896. Serial No. 609,186. (No model.)

To all whom it may concern:

Be it known that we,VILLIAM R. BILLINGS and EDWARD C. COLLINS, ofTaunton, in the county of Bristol and State of Massachusetts, haveinvented certain new and useful Improvements in Snow-Flows forStreet-Railways, of which the following, taken in connection with theaccompanying drawings, is a specification.

Our invention relates to snow-plows for street-railways, and especiallyto the mechanism for operating and controlling the wings or pivotedextensions of the plowshares, and is an improvement upon the inventionshown and described in the Letters Patent No. 527,523, granted toFrancis IV. Dean and William E. Mathews October 16, 1894; and itconsists in certain novel features of construction, arrangement, andcombination of parts,which will be readily understood by reference tothe description of the accompanying drawings, and to the claims heretoappended, and in which our invention is clearly pointed out.

Figure 1 of the drawings is a transverse vertical section through aportion of one sidel of a snow-plow embodying our invention and showingin full lines the position of the wing when thrown out of action bybeing raised and folded intoga position parallel, or nearly so, to theside of the car-body, and also showing in dotted lines the position ofthe same parts when the wing is dropped to its lowest position and swunginto operative position. Fig. 2 is a horizontal section through aportion of the car-body on line :c 0o on Fig. 1 and showin g in plan thewin g in operati ve position.

In the drawings, A is the sill of the carbody, B one of the side walls,C the fioor of the car, D the housing 'for the axle-box, E an angle-ironconnecting the housings on the same side of the car, and F is a smallportion of the'main body of the plowshare, all of which parts areconstructed and arranged substantially as shown and described in theLetters Patent before cited.

G is the wing or pivoted share extension, connected to themain'plowshare by means of the vertical rod ce, mounted in fixed ears bon said main plowshare, and the bearings@ c,

secured to said wing and fitted to and movable circumferentially andvertically on said rod, substantially as in said before-cited patent.

The wing Gis held in its expanded or operative position by the link Il,provided at its ends with eyes, one of which is engaged by the eye l,firmly secured in a fixed position to the angle-iron E, and the oppositeend of which engages the eyebolt or hook J, secured in a fixed positionto the wing G, as 6c shown.

The wing G has secured to its inner face the wooden battens d d and themetal angleiron batten e, to the latter of which the eyebolt or hook Jis connected by means of its stand J and suitable bolts, as shown.

A plate f, carrying at its upper end the metal ring g, is secured to theinner side of the wing G, and said ring has secured thereto one end ofthe rope h, which passes over the 7o sheave o', mounted in the stand K,secured to the inside of the wall of the car-body, as shown, and hassuspended from its other end the weight L, fitted to slide in guidewaysM, secured to the inside of the wall of the carbody, and adapted topartially counterbalance the weight of the wing G to such an eX- tentthat a person by placing his foot upon the pin j, proj ectinginward fromsaid weight, and pressing downward thereon may raise 8o the wing G t-othe eXtreme of its upward movement, during which movement the link H ismoved upward about its connection to the eye I into and slightly past avertical position, when the wing G assumes the raised and foldedposition parallel to the side of the car-body, as vshown in Fig. 1. Thewing G will remain in such raised and folded position without beingotherwise secured, while the car remains at rest by virtue of the factthat 9o the upper end of the link His thrown inward beyond a positionperpendicularly above the center of the eye I, but to prevent the jar ofthe car displacing it when in operation it is necessary to lock or latchsaid wing in its raised and folded position, when it is not required tobe in operation, while the main plowshare is in operation.

N is a three-armed lever pivoted to a stand O, secured to the outside ofthe wall of the Ioo car-body, through which one arm of said leverprojects into the interior of the car and is provided at its end with aroughened pad la, While the opposite horizontal arm projects outward, isweighted atits outer end, and provided with the downwardly-projectinglug or catch Z to engage the outer face of the wing G, as shown in Fig.l.

The pendent arm m of the level' N is so formed as to rest against theside of the carbody at m when in its normal position, and is held insuch contact by the action of gravity until displaced by force.

lVlien the wing G is raised and moved inward by depressing thecounterweight L, the metal plate or angle-iron fn, secured to the upperedge of said wing, strikes the outer inclined surface of the catch orlug Z and raises the weighted outer end' of the outer horizontal arm ofthe lever N to permit the edge of said wing to pass said catch, when theweighted end of said lever will fall with the catch Z outside of theangle-iron n and effectually prevent the wing G being moved outwardagain until said catch is raised. lVhen it is desired to drop the wingand move it into operative position, the operator, standing inside theear, places his foot upon the pad k of the lever N and depresses itsharply to disengage the catch Z and cause the knuckle 0 of the pendentarm m to strike the inner surface of the angle-iron e with a sharp blowand move the wing G outward till the upper end of the link H is inclinedoutward to such an extent that the force of gravity acting upon saidwing will cause it to fall into its lowest and operating position.

The main plowshare and the mechanism for controlling its operation maybe of the same construction as shown and described in the before-citedpatent or of any other suitable construction, but as they do notconstitute a part of our present invention they are not shown ordescribed in our present application.

The operation of our invention will be readily understood from theforegoing without further description here.

It is evidentthat a chain may be substituted for the rope or cord 7Lwithout affecting the principles of our invention.

Vhat we claim as new, and desire to secure by Letters Patient of theUnited States, is

l. In a snow-plow, the combination of a share extension-wing pivotallyconnected to the main plowshare, and adapted to be raised relative tosaid main share and moved about said pivotal connection; a sheavemounted in the side of the car-body; a cord or chain connected at oneend to said extension-wing and moved about said pivotal connection, and

raised relative to said main share; a link pivoted at one end to a fixedpart of the plowframe, and at its other end to a fixed connection tosaid wing, and adapted to be moved from a horizontal, to a verticalposition; a sheave set in the side wall of the carbody; a counterweightfitted to a suitable guide 'within said car-body; a cord or chainpassing over said sheave, and connected at one end to said shareextensiolrwing, and at its other end to said weight; and means fordepressing said weight and 'raisin g said wing by the pressure of theoperators foot.

In a snow-plow, the combination. of a share extension-wing pivotallyconnected to the main plowshare, and adapted to be raised relative tosaid main share and moved about said pivotal connection; means forraising said wing relative to said main share, and moving it about itspivotal connection thereto 5 a locking-leverpivoted to the wall of thecarbody, and provided, outside of said car-body, with a catch toautomatically engage the upper edge of said wing when in raised andfolded position, and on the inside of said car body with a pedal-arm bywhich said catch may be disengaged from said wing by the 0perator withinthe car; and means for automatically impellin g said wing away from saidcar-bod y when released.

4. In a snowplow, the combination of the pivoted wing G; means forraising said wing and moving it about its pivotal axis; the three-armedlever N, one arm of which is provided with the foot-pad 7o, another armwith the catch Z, and the third with the knuckle 0, all constructed,arranged and operating substantially as described.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, on this 9th day of October,A. D. 1896.
